On clearing agricultural land from undesirable vegetation as a way to improve soil fertility

Land, Soil and Vegetation Resources in India

The nation’s strength, be it social, economic or political depends mostly on the available resources and their proper utilisation. But what is a resource? In simpler terms, resource is the matter or substance which satisfies human wants at a given time and space. Before any element can be designated as resource three basic pre-conditions must be satisfied. They are the knowledge, technical skil...

Soil Fertility Decline on Agricultural Plantations in the Tropics

Maintaining the soil chemical fertility is a key prerequisite to sustain crop productivity in the tropics. Several studies perceive that soil fertility decline is widely spread in tropical regions and that it is caused by inadequate nutrient replenishment and high losses as compared to natural ecosystems. Although this has been recognised for some decades, there is a need for hard data on soil ...

Angiostasis as a way to improve immunotherapy.

Tumours express tumour-associated antigens that are recognised as self-antigens precluding the induction of effective anti-tumour immune responses. Inflammatory conditions which facilitate appropriate antigen presentation and reduce the immuno-suppressive micro-milieu may break tolerance. However, tumours have evolved mechanisms to escape cytotoxic T-cell attack by expressing inhibitory molecul...

Clearing the way to implantation.

The endocrine symphony known as the reproductive life cycle consists of a complex series of hormonally driven “movements.” The sole rationale for the reproductive cycle is the generation of a fertilizable ovum and, contingent upon fertilization, the establishment of implantation and of an ongoing gestation. Although fecundity rates vary among species, there can be little question as to the ongo...
